AUTOMATIC GRAiN SAh/IPLER.

SPECIFICATION forming part of Letters Patent No. 259,586, dated June 13,1882.

Application filed March '23, 188:2.

To all whom "it may concern:

Be it known that I, Wasnmeron HAWES, of Port Richmond, in the county ofRichmond and State of New York, have invented certain new and usefulImprovements in Sampling Attachments to Devices or Apparatus forDelivering and Measuring Grain and other Substances, of which thefollowing is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figures 1 and 2 represent partly sectional elevations in planes at rightangles with each other of a seed or grain measuring apparatus arrangedon a platform-scale, with sampler or toller attached.

This invention, although applicable to sampling or tolling varioussubstances besides seed or grain, including diflerent liquids, will herebe described more particularly with reference to sampling seed or grainas delivered in bulk from an elevator or otherwise, and which mayafterward be reconveyed byan elevator or other means to its place ofdeposit.

My invention consists in a sampler or toller which will sample fixed,measured, and equal quantities each time it is operated, and which willoperate automatically or at stated intervals, and when attached to ameasuring-receiver will act in concert with the valve used to dischargethe measured load from said receiver, whereby greater accuracy insampling is obtained, and the same motion that is used to open or closethe discharge-valve of said re ceiver actuates the sampler.

The invention also consists in a novel construction ofsuch automaticmeasuring-sampler with inlet and outlet valves operatingin reverserelation with each other, and in special combinations of devices forcontrolling the discharge-valve of the receiver, so that it will act inconcert with the sampling device, and whereby said discharge-valve willbe locked or held closed when the measuring-receiver is being filled,and will be quickly released and opened when it is required to dischargethe measured load therefrom.

In the drawings, A indicates the receivinghopper of a grain-measuringapparatus, pro- (No model.)

vided with the usual valve, 1), and handle 0 for opening and closingsaid valve by hand to control the supply of grain to themeasuring-receiver B beneath. The hopper A has a fixed position, but thereceiver B is seated upon the vplatform G of a platform-scale, O D, sothat accordingly as said receiver is empty or is loaded with a givenquantity of grain, as indicated by the weighted scale, it is free torise and fall with the said platform. Every time the speci fiedmeasurement, by weight, of grain in said receiver has been made to tipthe scale the usual delivery-valve, E, at the bottom of said receiver,is opened to discharge the contents of said vessel. This valve is openedand closed, to put the measuring-receptacle B either into a receiving ordischarging condition, by means of a rod, cl, attached to a crank, c, ona rockshaft,f, arranged within the body of the receiver and extendingout through its side, with a handle, g, on its exterior end foroperating it. The crank c is so set in relation with the valve E thatwhen said valve is closed the crank reaches or passes slightly beyondits upper dead-center, and may at such point come in contact with a stoph. By thus arranging the crank e relatively to the valve E said valvewhen shut will be locked or held closed during the time the receptacle Bis receiving its measured quantity of grain, and will he suddenlyreleased and opened by the weight of the grain .to discharge the load sosoon as the handle g is moved to start the crank back beyond itsdead-center. This mode of operating the discharge-valve E insures bothaccuracy and dis- This tube is closed at its inner and outer ends I byslide-valves 7r 7c, and is of a suitable capacity'to hold a givenquantity of grain, thereby forming a measuringsampler. Said valves maywork between V-shaped guides at their side edges, and by their slidingaction present but little resistance to the grain. They are operated bymeans of rods 1 l and eccentries at m on the rock-shaft f, so that theyact in concert with the general delivery valve E, and are actuated bythe same motion, thus dispensing with all additional sampling labor. Theeccentrics m m are so set that the valves k k operate simultaneously inreverse directions,wh ereby when the one valve is open the other isclosed, and so that when the receptacle B is receiving grain and thegeneral discharge valve E is closed the outer slide valvek, is alsoclosed, and the inner slide-valve, 7c, is open to allow grain to passinto and fill the sampler. On the other hand, when the discharge-valve Eis open to deliver the measured load of grain from the receiver, theinner slidevalve, 70, is closed and the outer slide-valve, 7c, is open.Said slide-valves should have sufficient lap to give time for theopening and closingof the general discharge valve E. By means of thissampler or toller G samples, each of which has the same measurement, areautomatically taken at stated intervals-that is, every time themeasuring-receptacleB receives and discharges a load-which samples, whenafterward mixed, may be resampled to give a correct average of thequality of the whole.

In cases where the grain is passed through a delivery duct or chamberwithout being weighed or measured, excepting by the car or boat load,the measuring-sampler G may beepplied to said duct or chamber toautomatically draw measured samples at stated intervals by a uniformmotion, which may be a continuous revolving one, of the shaftf; or,wherethe material to be measured and sampled does not usually vary in weightfor a given bulk, the measuring-receiver may be a fixture and theplatform-scale be dispensed with.

In such arrangement, as in the apparatus shown in the drawings, theautomatic measuring-sampler G, with its reversely-operating valves atits opposite ends, should be applied to tap said receiver, ashereinbefore described.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In an apparatus for delivering ordelivering and measuring grain and other substances in bulk, thecombination, with the receptacle or chamber down through which thematerial being measured or delivered passes, of an automatic measuringsampler or toller arranged to tap said receptacle or chamber, andprovided with reversely-operatin g valves at its opposite aaaaac ends,and means for actuatingthe same at intervals, substantially asspecified.

2. The combination, with a measuring-receiver having a discharge-valveat or near its lower end, of an automatic measuring sampler or tollerarranged to tap said receiver, and provided with reversely-operatingvalves at its opposite ends, and mechanism for actuating thedischarge-valve of the measuring-receiver and valves of themeasuring-sampler in timely relation with each other and by the sameapplication of power to a prime mover or shaft, essentially as and forthe purposes herein set forth.

3. In apparatus for measuring grain and other substances, thecombination, with a. measuring-receiver having a discharge-valve at ornear its bottom, and a platform-scale on which said receiver is carried,of an automatic measuring sampler or toller arranged to tap saidreceiver, and provided with reversely-operating valves at its oppositeends, and mechanism for actuating, by the same application of power, thedischarge-valve of said receiver and valves of the measuring-sampler intimely relation with each other, substantially as specified.

4. The combination, with the measuring-receiver B, provided with adischarge-valve, E, of the rock-shaftf, capable of operation from theexterior of said receiver, the rod or connection cl, and the crank 0,arranged in relation with said valve as herein described,and whereby thevalve is held closed by the crank when reaching its upper dead-center,and is quickly released and opened in the back action of the crank,essentially as specified.

5. The measuring sampler or toller G, fitted with the slide-valves k kat its opposite ends, in combination with the reversely-set eccentrics mm, the rock-shaft f, and the rods or connectionsl Z, substantially asspecified.

6. The combination, with the measuring-receiver B, provided with adischarge-valve, E, of the rock-shat'tf, the rod 07, and crank e, thereversely-set eccentrics m m upon said shaft, the rods 1 Z, and themeasuring sampler or toller Gr, with its opposite end valves, 7a k,essentially as and for the purposes herein set forth.
